Window-screen



UNITED STATES PATENT OFFICE.

WINDOW-SCREEN.

Specification forming part of Letters Patent No. 52,726, dated February 20, 1866.

To all whom it may concern.'

Be it known that I, ABNER B. MAGOUN, of West Hanover, in the county of Plymouth and State of Massachusetts, have invented an Adjustable Window-Screen and I do hereby declare the same to be fullyT described in the following specification and represented in the accompanying drawings, of Which- Figure l is a front elevation; Fig. 2, a horizontal aud transverse section; Fig. 3 is a Vertical and transverse section of it.

The principal object or purpose of my in- Vention is to allow air to pass into a room, and to prevent the entrance of flies or other insects therein when the screen is applied to a wiudow. The peculiar construction of the screen enables it to be adjusted to almost any window-frame of ordinary width.

In the said drawings, A and B are two square or rectangular frames, each being covered with muslin or wire-gauze. Each frame has its outer eud bar, a, made thicker than its inner end bar, b, and arranged with respect to the latter and the side bars, c c, in manner as shown in the drawings.

A metallic guide or thin strip ot' metal, bent in section, as represented in Fig. 2, is fastened to the outer edge of each of the side bars, c c, of one of the frames. These guides receive Within and between them the side bars of the other frame, and enable the two frames t0 be slid on one another, the whole forming an adjustable screen capable of being Iitted to window-frames of different widths.

I am aware of the window-screen which constitutes the subject of Letters Patent 'No. 37,779, and dated September 24, 1863, and consequently make no claim to the same, my invention diiering materially from it.

What I claim as my invention is My improved adjustable screen made of the two frames, their guides, and two separate coverings, arranged and combined substantially as and so as to operate as described.

ABNER B. MAGOUN.
